Even though most of my writing is fantasy fiction, there is still a good bit of research to be done, especially when I want to check my information on a mythological creature or god. Since I’ve studied mythology for the better part of two decades, a good bit of it is in my head, but there are still times I need to double check something.
One of my favorite sites for doing this is http://www.sacred-texts.com. They’ve published public domain works of just about any text on religion and mythology that you can imagine, and it’s a great place to kick back and read. Some of my favorites are the texts written in the late 1800’s and early 1900’s with the woodcut illustrations. Of course, some of the more scientific texts are outdated, but they’re still great reading.
